-STOPPER FOR 'RECEPTACLES.

SPECIFICATION forming part of Letters Patent No. 769,775, dated Sep b 13, 1904. Application filed May 23, 1904. Serial 1ft. 209,283. (No nioclel.)

To all whom it may concern.-

Be it known that I, EMIL O. STAUDINGER, a citizen of the United States of America, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Stoppers for Receptacles, of which the following is a specification.

This invention relates to packing and storing vessels, and particularly to a class thereunder known as stoppers.

An object of this invention is to provide novel means for effecting the closing of a spout of a receptacle in order to prevent the entrance of fire to the receptacle and also to prevent the evaporation of the contents of the said receptacle.

Furthermore, an object of the invention is to provide novel means for withdrawing the stopper from the spout with the elevation of the receptacle by the hand of an operator and the provision of means for permitting proper movement of the stopper independently of its carrying member when it is withdrawn from the spout.

Finally, an object of the invention is to produce a stopper and closing means which will prove efficient and satisfactory in use, strong and durable, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and specifically claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, wherein like characters denote corresponding parts throughout the several views, in which- Figure 1 is a view in perspective of a receptacle, its stopper, and the operating means embodying the invention. Fig. 2 is a similar view showing the stopper seated to close the spout.

In the drawings, A indicates the receptacle, which may be metallic or wooden, and B is a spout which may be of any ordinary construction and which may be located at any convenient position on the head of the receptacle.

The upper surface of the head of the receptacle is provided with ears O, having apertures 0 for the reception of the pintles D of the arm (Z, the said arm d being rocked with relation to the spout B, as occasion requires. Transversely of the arm (Z is a short rod E, which is secured to the said arm in any convenient way, and the said rod affords means for enreceptacle by solder, orit may be secured by p a clip or in any other suitable manner. The metal from which the spring is formed has its portions diverging slightly and wound around the pintle D and having its ends extending upwardly into engagement with the arm d, to which the said ends are secured by brazing or in any suitable manner, or, if desired, the ends need not be secured to the arm, but may by resting on the upper surface of the bar E have sufficient anchorage to prevent their dislodgement and to cause their operation in the proper way. As a matter of fact the portions of the spring need not be wound around the pintle, and the two portions of the spring which are divided may consist of two separate pieces.

On the outer end of the arm (Z is carried a stopper G,which has its lower end tapered to a point, and intermediately the length of the said stopper is an annular flange g, of rubber or other yielding material, which arrests the downward movement of the said stopper by reason of its engagement with the wall of the spout, and the said engagement also effects .the sealing of the spout and serves to prevent evaporation of the contents of the receptacle. This stopper G is composed of any suitable material; but it is preferable that the said stopper be weighted or have a weight greater than that of wood in order that it will gravitate readily and seal the spout when the arm cl is released; but it is mypurpose tohave the spring F assist in causing the stopper to enter the spout, and it is also my purpose to have the spring retain the stopper in place in case the receptacle is tilted or upset. The stem H is pivoted to the stopper in order that the said stopper may have free movement, and the said stem has a bifurcation It in its end, in which the end of the arm cl is pivoted by means of the pin it. A guide-rod I has one end anchored in the lower end of the stopper,and the said guide-rod depends into the receptacle at all times, but is partially Withdrawn With the withdrawal of the stopper. The end which is not withdrawn is caused to engage the wall of the opening of the spout, and as the said arm and stopper descend the guide-rod serves to cause the stopper to travel in such relation to the spout as to insure the said stopper being seated to seal the opening of the spout. The stopper is secured on the stem by means of the pin J, (shown in dotted lines in Fig. 2,)

which passesthrough the piece j of the stopper and through the said stem.

A handle K is attached, preferably near the bottom of the receptacle, to be used when the operator desires to pour the contents of the receptacle.

In operation the bar E is grasped and the arm 03 is swung on its pivot until it stands approximately vertical, and in which position the stopper is removed from the spout, as shown in Fig. 1, and then by grasping the handle K the receptacle may be tilted to any desired angle and manipulated. When the receptacle is again brought to stand upright or to an upright position and the arm dis released, the weight of the stopper, augmented by the action of the spring, causes the seating of the stopper and the sealing of the spout.

Having fully described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with areceptacle having a spout, an arm pivoted with relation to the receptacle, a weighted stopper carried by the said arm and a guide depending from the stopper into the receptacle through the spout, substantially as described.

2. In combination with a receptacle having a spout, an arm pivoted with relation to the spout, a weighted stopper carried by the arm, a guidedepending from the stopper into the receptacle through the spout, and a spring exerting pressure to hold the arm normally depressed.

3. In combination with a receptacle having a spout, an arm pivoted with relation to the spout, a rod secured transversely of the arm, a spring for holding the arm normally depressed and a weighted stopper pivoted to the arm, substantially as described.

4L. In combination with a receptacle having a spout, an arm pivoted with relation to the spout, a rod secured transversely of the arm, a spring for holding the arm normally depressed, a Weighted stopper pivoted to the arm, and a guide-rod depending from the inner end of the stopper into the receptacle through the spout, substantially as described.

5. In combination with a receptacle having a spout, an arm pivoted to the receptacle in certain relation to the spout, a stopper carried by the arm, a weight provided for the stopper, a depending rod carried by the stopper, extending into the receptacle through the spout, a spring anchored to the top of the receptacle and extending around the top of the arm and exerting a pressure on said arm, substantially as described.

In testimony whereof I afiix my signature, in the presence of two witnesses, this 19th day of May, 190 i.
